The explanation ＞ of ＜ status transition
Then, the process to present embodiment illustrates.
First, with reference to Fig. 8, the summary of the status transition to present embodiment illustrates.
Fig. 8 is the flow chart of the summary of the status transition of process of exchange camera lens representing present embodiment.
First, in the case of the connection of the main power source of camera body 100 with respect to camera body 100, or, in photograph In the case that the main power source of body 100 is just provided with adapter 300 in the on state, adapter 300 passes through camera body 100 control, executes " camera lens start up process " (step S100).
Here, " camera lens start up process " is such as camera body 100 judging with respect to the dismounting of camera body side interface 101 Process, adapter 300 and the initialization process, the power supply control of each power-supply system that exchange camera lens 200 being installed on adapter 300 Process etc..In addition, for example, in this camera lens start up process, camera body 100 obtains via adapter 300 and is installed on photograph The exchange species of camera lens 200 of body 100 and the information of specification (function).With regard to this camera lens start up process, in " camera lens described later It is described in detail in start up process " (Figure 12).
When camera lens start up process completes in the step s 100, adapter 300 passes through the control of camera body 100, transition Arrive " camera lens normal process " (step S200).

(explanation of the order data communication of camera lens normal process)
Then, the order data communication to execution in camera lens normal process (step S200 of Fig. 8) illustrates.
Fig. 9 is the figure representing one of the communication sequence of order data communication of camera lens normal process example.
This figure is the photographing unit to exchange camera lens 200 (CPU camera lens) and camera body 100 connects via adapter 300 The figure of an example of order data communication is represented as a example system 1.Adapter control unit 310 with photographing unit control unit 110 Between, can normally execute the communication in cycle, by executing the communication in this cycle, according to asking from photographing unit control unit 110 Ask, the shot information obtaining from lens control portion 210 (information of optical system 220 etc.) is sent to photographing unit control unit 110.
For example, in " the camera lens normal process " shown in Fig. 9, the first adapter communications portion 312 is held with asynchronous relation Row is exchanging, with cycle T f (the first communication cycle), first being communicated between the lens control portion 210 that camera lens 200 possesses Periodic communication, communicated in the photographing unit control unit 110 possessing with camera body 100 with cycle T m (the second communication cycle) Second periodic communication.
First adapter communications portion 312 and the first camera lens communication unit 212 are held with cycle T f (for example, the cycle of every 64msec) The communication (the first periodic communication) (step S2010, S2020) of row first data communication system D1L.
Here, the communication (first periodic communication) of the first data communication system D1L of this camera lens normal process is referred to as " mirror Head proper communication ".By this camera lens proper communication, the first adapter communications portion 312 obtains camera lens from the first camera lens communication unit 212 Information (information of optical system 220 etc. (first information)).
In addition, the first adapter communications portion 312 is based on the shot information obtaining in step S2010, generate to the first photograph The shot information (information of optical system 220 etc. (the second information)) (step S2015) that camera communication unit 112 sends.For example, One adapter communications portion 312 in step S2010 obtain shot information (information of optical system 220 etc.) data to accord with The mode closing the communication standard of the first data communication system D1b carries out data conversion, generates to 112, the first camera communications portion The information sent.
Equally, the first adapter communications portion 312 based in step S2020 obtain shot information (optical system 220 Information etc.), carry out data conversion and generate the information (step S2025) sending to the first camera communications portion 112.
That is, the first adapter communications portion 312 is according to the communication timing (the communication timing of cycle T f) of camera lens proper communication, raw Become the shot information (information of optical system 220 etc.) sending to the first camera communications portion 112.
For the communication of the first above-mentioned data communication system D1L, the first adapter communications portion 312 and the first photographing unit Communication unit 112 is non-with communication (the first periodic communication) cycle T f exchanging between camera lens 200 of the first data communication system D1L Synchronous cycle T m (for example, cycle of every 16msec) executes the communication (the second periodic communication) of the first data communication system D1b (step S1010, S1015, S1020, S1025).This communication cycle Tm is than the communication cycle of communication cycle Tf high speed.
Here, by the communication (second periodic communication) of the first data communication system D1b of this camera lens normal process referred to as " just Normal open is believed ".This proper communication comprises camera lens dismounting detection process (camera lens dismounting detection) and (below, normal data communication is processed Referred to as " normal data communication ").
The camera lens dismounting detection process of each step are the first adapter communications portions 312 according to from the first camera communications portion 112 camera lens dismounting detection instruction orders to respond the process of testing result.First adapter communications portion 312 is based on whether have From the response of the camera lens proper communication of the first camera lens communication unit 212, the dismounting exchanging camera lens 200 is detected, and will detect Result is sent to the first camera communications portion 112.
The normal data communication of each step is that acquirement the first adapter communications portion 312 of the first camera communications portion 112 generates Shot information (information of optical system 220 etc.) communication process.That is, in normal data communication, the first camera communications Portion 112 sends the request life of the transmission of request shot information (information of optical system 220 etc.) to the first adapter communications portion 312 Order, by the response from the first adapter communications portion 312 receiving this request command (from adapter sending out to camera side Send), carry out the reception of the shot information (information of optical system 220 etc.) carrying out self-exchange camera lens 200 via adapter 300 (acquirement) is processed.This request command is termly sent in normal data communication, the therefore first camera communications portion 112 whenever When carrying out this normal data communication, all repeat acquirement (reception) action of shot information.
For example, the first camera communications portion 112 passes through the normal data communication of step S1010, obtains the first adapter and leads to Letter portion 312 is based on shot information (information of optical system 220 etc./the obtaining before the camera lens proper communication of step S2010 One information) and the shot information (the second information) of generation.In addition, the first camera communications portion 112 passes through step S1015, S1020 Normal data communication, obtain the first adapter communications portion 312 based in the camera lens proper communication of step S2010 obtain mirror Header (information of optical system 220 the etc./first information) and generate shot information (the second information).In addition, the first photograph Machine communication unit 112 passes through the normal data communication of step S1025, and the first adapter communications portion 312 that obtains is based in step S2020 Camera lens proper communication in obtain shot information (information of optical system 220 etc.) and generate shot information.
That is, the first adapter communications portion 312 with cycle T m of normal data communication by shot information generated as discussed above It is sent to the first camera communications portion 112 (response).
So, in order data communication, adapter control unit 310 is taken based on the camera lens proper communication by cycle T f The shot information (information of optical system 220 the etc./first information) carrying out self-exchange camera lens 200 obtaining, generates to photographing unit control The shot information (the second information) that portion 110 sends.In addition, adapter control unit 310 passes through the normal data communication of cycle T m, will The shot information (the second information) generating is sent to photographing unit control unit 110.
Thus, adapter control unit 310 can be by being in cycle T m of asynchronous relation with respect to cycle T f Normal data communication, the shot information camera lens proper communication by cycle T f being obtained generation smoothly and is reliably transmitted to Photographing unit control unit 110.
Thus, adapter control unit 310, can be according to from photographing unit by being communicated with photographing unit control unit 110 The request of control unit 110, the shot information obtaining from lens control portion 210 is successfully sent to photographing unit control unit 110.
In addition, using Fig. 9 to the first adapter communications portion 312 according to the communication of camera lens proper communication timing (cycle T f Communication timing) generate and enter to the process of the shot information (information of optical system 220 etc.) of the first camera communications portion 112 transmission Go explanation, but be not limited to this.For example, the first adapter communications portion 312 can also be fixed according to the communication of normal data communication When the communication of cycle T m (timing) generate the shot information (information of optical system 220 sending to the first camera communications portion 112 Deng).
Thus, the shot information (light that adapter control unit 310 can obtain from the camera lens proper communication by cycle T f Information of system 220 etc.), according to the timing of cycle T m being in asynchronous relation with respect to cycle T f, generate to photograph The shot information that machine control unit 110 sends, and the shot information of generation can be sent to by photographing unit by normal data communication Control unit 110.
In addition, using Fig. 9 to the first adapter communications portion 312 using with cycle T f of the communication in lens control portion 210 and The process being in asynchronous relation with cycle T m of the communication of photographing unit control unit 110 is illustrated but it is also possible to adopt week Phase Tf and cycle T m are in the process of synchronized relation.
(explanation of camera lens proper communication)
" the camera lens proper communication " being communicated with cycle T f is specifically divided within a cycle (for example, 64ms cycle) Repeatedly communication (time required for for example, communicate/once communicating for every eight times is about 8ms) communicates.This multiple communication bag contains the One adapter communications portion 312 is used for obtaining the communication of information and from the first adapter communications portion 312 to mirror from lens control portion 210 The communication of head control unit 210 output information (setting instruction).
First adapter communications portion 312 is carried out repeatedly in camera lens proper communication between the first camera lens communication unit 212 Communication, obtains shot information (information of optical system 220 or the letter of aperture unit 250 from the first camera lens communication unit 212 every time Breath etc./the first information).In addition, the first adapter communications portion 312 is using by multiple communication and mutual in the shot information of acquirement Time middle multiple shot information obtaining differing, generation is sent to the first camera communications portion 112 with normal data communication Shot information.Then, the first adapter communications portion 312 is according to the request from the first camera communications portion 112, the mirror that will generate Header (the second information) is sent to the first camera communications portion 112.
Figure 10 is to represent to be divided into one of the communications command repeatedly communicating and communicating example within a cycle of camera lens proper communication Figure.
As shown in the drawing, camera lens proper communication has the communications command D1～D8 of such as transceiving communication data, in camera lens just The period in one cycle of normal open letter, communicated successively.In example shown in this figure, in a period of a cycle, by according to Secondary communications command D1～D8 to camera lens proper communication communicates, and to carry out eight communication.
In addition, in camera lens proper communication, existing in the communications command D1～D8 of transmission or reception communication data and be used for Adapter 300 side obtains the order of the shot information related to exchanging camera lens 200 and for from adapter from exchange camera lens 200 side draw 300 lateral camera lens 200 sides that exchange send information or the order of instruction (setting instruction).As for obtaining and exchanging camera lens 200 The order of related information, has the information for example to optical system 220 or to represent that the information of driving condition is communicated logical The communications command D6 of letter order D1, D4, D5, the acquirement information related to electromagnetism aperture.In addition, as exchange camera lens 200 sides send information or the order of instruction (setting instruction), have the information (example to the operating state representing camera body 100 As indicated whether to have carried out the information of the half-press press operation to shutter release button) the communications command D2 that communicated, to straight-through Communications command D3 that the set information (set instruction) of communication is communicated, to vibration Restrained Control (control of VR camera lens 223) phase Communications command D7, D8 that the instruction (setting instruction) closed is communicated.It is additionally, since the function of exchanging camera lens because exchanging camera lens (exchange camera lens 200 or other exchange camera lens) specification and different, therefore to by exchange camera lens specification (function) (root According to exchanging the species of camera lens, pattern) and the communications command that selects from communications command D1～D8 is communicated.
For example, mirror is exchanged by the presence or absence of the presence or absence of VR camera lens 223 (the presence or absence of anti-vibration functions) or electromagnetism aperture function etc. The specification (function) of head, does not carry out the communication of unnecessary communications command.
That is, the first adapter communications portion 312 passes through multiple communication, and the information of optical system 220 is divided into multiple information And obtain, generate the information of the optical system 220 that the corresponding information of multiple information being obtained with segmentation is summarized as.
In addition, information corresponding with multiple information is that according to communication standard etc., the plurality of information is carried out with the letter of data conversion Breath etc..
First adapter communications portion 312 pass through within a cycle of camera lens proper communication successively to eight kinds of communications command D1～ D8 is (as described above, wherein four kinds communications commands D2, D3, D7, D8 are for sending information and instruction to exchange camera lens 200 side Order, remaining four kinds of communications commands D1, D4, D5, D6 are from the order exchanging camera lens 200 acquirement information) communicated, will be with light The information of the system 220 correlation information related to aperture unit 250 and other various shot information are divided into four kinds of information (being divided into four times) and obtain (reception), and to exchange camera lens 200 segmentation send four kinds of information, instructions.
In addition, the first adapter communications portion 312 information that segmentation obtains based on every four communications in the cycle, generate Information to the optical system 220 that the first camera communications portion 112 sends.Here, the first adapter communications portion 312 is in a cycle The information (information in other words, sending to the first camera communications portion 112) of the camera lens (for example, optical system 220) of interior generation It is not that each reception all generates each information of segmentation acquirement and is sent to camera body 100, but generate based within a cycle Split the full detail (if present embodiment, be then divided into four times and split the whole shot information receiving) that receives and The shot information sending, and the shot information being generated is sent to camera body 100.That is, the mirror sending to camera body 100 Header is not only the respective information of segmentation acquirement, but also is that receive four kinds of (four times) full details are summarized in one Rise (being to be summarized as one to the transmission of camera body 100) information (in other words, adapter 300 be not by from exchange camera lens 200 shot information receiving in four times are sent to camera body 100 in four times, but are once sent to camera body 100). Constituted by such, the communication frequency between adapter 300 and camera body 100 can be suppressed, the control of both sides can be mitigated The processing load in portion's (adapter control unit 310 and photographing unit control unit 110).
In addition, the first adapter communications portion 312 is based on shot information (for example, the information of optical system 220), by " just Regular data communicates " (with reference to Fig. 9), generate the shot information (optical system 220 for sending to the first camera communications portion 112 Information), described shot information (for example, the information of optical system 220), is based on predetermined form and by " camera lens is normal Communication " (with reference to Fig. 9) and obtain.
Here, predetermined form is by between the first adapter communications portion 312 and the first camera communications portion 112 The communication standard of order data communication of one data communication system D1b and predetermined form, and are to define transmission optical system The form of the specification that the data of 220 information is constituted etc..For example, the information as optical system 220 is it is stipulated that there is expression optical system The information of species of system 220, the information of driving condition representing focusing lens 222, the letter of the driving condition of expression VR camera lens 223 The specification that the data such as breath are constituted.
So, the first adapter communications portion 312 will by multiple communication, segmentation obtains and is in " camera lens proper communication " The shot information (information of optical system 220) of multiple information is converted to concludes (being summarized as one) based on predetermined form Information, is then sent by the once communication of " normal data communication ".That is, the first adapter communications portion 312 will be so that " camera lens is just The communication data of the communication format transmitting-receiving of normal open letter " is converted to the communication number of the communication format transmitting-receiving of " normal data communication " According to.
Thus, adapter 300 passes through to be installed on the camera body 100 with mutually different communication standard and exchanges camera lens Between 200, the information of optical system 220 exchanging camera lens 200 can be obtained and be sent to camera body 100.
In addition, in the above-described embodiment, to by several times and the shot information obtaining all is summarized as one and sends Example to camera body 100 is illustrated but it is also possible to be required for all.
For example, it is also possible to select repeatedly (for example, twice or thrice) several times in (in above-mentioned, four times) reception, then This information chosen is summarized as one and sends.
In addition, adapter 300 is due to being configured to the not only communication format according to " normal data communication ", but also according to next From the request command (analyzing its request command) of camera body 100, the shot information obtaining from camera lens 200 is combined as sending Content (in the way of meeting from the request of camera body 100) and send, therefore to from camera body 100 various please For asking order, also can correspond to.
(communication process that detected of driving condition to the driving factor (or optical system drive division) exchanging camera lens)
Then, the driving factor (optical system 220 or aperture unit 250) exchanging camera lens 200 or optical system are driven The communication process of the driving condition in portion 230 illustrates.
Adapter control unit 310 receive from photographing unit control unit 110 output control instruction (for example, first adapter lead to First acceptance division in letter portion 312 is received), the content of the control instruction being received according to it is (in the reception of the first acceptance division Hold), lens control portion 210 is sent for (in other words, the optical system in camera lens 200 is exchanged to optical system drive division 230 The driving factor such as 220 or aperture unit 250) be driven control lens control instruction (for example, the first adapter communications portion 312 the first sending part is transmitted).In addition, adapter control unit 310 is after have sent the instruction of this lens control, from mirror Head control unit 210 receives status information (for example, first adapter communications of the driving condition representing optical system drive division 230 Second acceptance division in portion 312 is received), it is then based on the content (the reception content of the second acceptance division) receiving, would indicate that The status information of the driving condition of driving factor is sent to photographing unit control unit 110 (for example, the first adapter communications portion 312 Second sending part is transmitted).
That is, adapter control unit 310 will be sent to lens control to the instruction of the lens control of optical system drive division 230 The status information of the driving condition representing optical system drive division 230 after portion 210, is obtained from lens control portion 210, then right Photographing unit control unit 110 sends its status information.
But, adapter control unit 310 have sent the camera lens driving beginning of instruction driving factor in lens control portion 210 In the case of control instruction (the first lens control instruction) (for example, in the case of sending from the first sending part), no matter the The reception of two acceptance divisions how, all compares camera control portion 110 and sends and represents that driving factor is status information in driving (from the Two sending parts send).
For example, lens control portion 210 when from adapter control unit 310 receive drive start lens control instruction when, just Instruction according to this control instruction is driving optical system drive division 230.In addition, lens control portion 210 according to start drive light Learn system drive portion 230, would indicate that the driving factor exchanging in camera lens 200 is that the status information of " in driving " is sent to adapter Control unit 310.
Here, adapter control unit 310 is when receiving this status information by camera lens proper communication from camera lens to wait, so Afterwards when normal data communication compares and constituted in the way of camera control portion 110 sends its status information of receiving, with respect to opening The timing (that is, in driving) of the driving of beginning optical system drive division 230, is its status information transmission in driving until would indicate that To photographing unit control unit 110, generally require the time (constant time lag being received by photographing unit control unit 110).
This is because, camera lens proper communication and normal data communication are in mutually asynchronous relation, and with different Cycle communicated.In addition also as, adapter control unit 310 is in order to be the positive normal open of camera lens to mutually different communication standard Communication between letter and normal data communication is relayed, and needs the conversion process of data.
So, adapter control unit 310 is being " to drive from the expression that is timed to of the driving starting optical system drive division 230 During the timing that the status information of disorder of internal organs " is received by photographing unit control unit 110, time lag can be produced.That is, in photographing unit control unit 110, although optical system drive division 230 has been in driving, results in generation and can not receive the state that expression is " in driving " The period of information.
In order to reduce above-mentioned time lag, adapter control unit 310 by optical system drive division 230 drive start Lens control instruction (first lens control instruction) be sent to lens control portion 210 (for example, sending from the first sending part) with Afterwards (afterwards), it is not to wait for the response from lens control portion 210 and (represent the sound of the status information of driving condition of driving factor Should) (for example, being not to wait for the reception of the second acceptance division), comparison camera control portion 110 sends and represents already at driving condition Status information (expression is the status information of " in driving " state).
In addition, the adapter control unit 310 of present embodiment is configured to for above-mentioned representing to drive the camera lens control starting After instruction processed is sent to lens control portion 210, then would indicate that the status information of " in driving " is sent to photographing unit control unit 110.With regard to this order, for example, it is also possible to improve the sequence of movement of adapter control unit 310 as follows, i.e. will be upper While the lens control instruction stated is sent to lens control portion 210, the status information of " in driving " is sent to photographing unit control Portion 110 processed.
On the other hand, in the case that the driving in optical system drive division 230 stops, adapter control unit 310 is from mirror Head control unit 210 obtains the response (status information) representing that optical system drive division 230 is in halted state, then to photographing unit Control unit 110 sends the status information representing its " driving halted state ".That is, optical system is being driven by adapter control unit 310 Dynamic portion 230 drives in the case of stopping, and (have received expression from lens control portion 210 after the halted state confirming reality After the response of its order), comparison camera control portion 110 responds its order.
Figure 11 be the driving condition representing to optical system drive division 230 (or above-mentioned driving factor) detected logical The figure of one of letter order example.
With reference to this figure to adapter control unit 310 by the driving of optical system drive division 230 (or above-mentioned driving factor) The process of state communication illustrates.
In addition, the first camera communications portion 112 and the first adapter communications portion 312 carry out normal data communication with cycle T m (step S1032, S1036, S1038, S1040).In addition, the first adapter communications portion 312 and the first camera lens communication unit 212 are with week Phase Tf carries out camera lens proper communication (step S2034, S2038).
First, controlled the situation exchanging the optical system drive division 230 that camera lens 200 possesses by photographing unit control unit 110 Under, the lens control instruction controlling optical system drive division 230 is sent to the first adapter and leads to by the first camera communications portion 112 Letter portion 312 (step S1030).For example, the first camera communications portion 112 sends makes the position of focusing lens 222 move to target Lens control instruction (driving sign on) of position.
Then, the first adapter communications portion 312 by the lens control receiving instruction (driving sign on) be converted to Lens control instruction (driving sign on) that first camera lens communication unit 212 sends, then by the lens control instruction after conversion (driving sign on) is sent to the first camera lens communication unit 212 (step S2030).In addition, the first adapter communications portion 312 is inciting somebody to action After lens control instruction is sent to the first camera lens communication unit 212, the not driving condition of detection optical system drive division 230, and It is that driving condition is set as " in driving " (step S2032).For example, the first adapter communications portion 312 is according to making focusing lens 222 position moves to the lens control instruction of target location, would indicate that the status information of the driving condition of focusing lens 222 sets It is set to " in driving ".
First adapter communications portion 312 passes through normal data communication, and the state information response being set as " in driving " is arrived First camera communications portion 112 (step S1032).First camera communications portion 112 is led to by the normal data of step S1032 Letter, to detect that status information is the situation (step S1035) of " in driving ".
In addition, the first camera lens communication unit 212 receives the mirror sending in step S2030 from the first adapter communications portion 312 Head control instruction.The optical system control unit 211 in lens control portion 210 is based on lens control and instructs (driving sign on), comes Control optical system drive division 230 so as to start to drive (step S3030).For example, optical system control unit 211 is according to making tune The position of zoom lens 222 moves to the lens control instruction of target location, controls optical system drive division 230, starts focusing lens 222 driving.
In addition, optical system control unit 211 starts the drive of focusing lens 222 according to control optical system drive division 230 Dynamic, the status information that the inside exchanging camera lens 200 is had is set as that the driving condition representing focusing lens 222 is in driving " in driving " (step S3032).
Then, the first camera lens communication unit 212 is responded in this step S3032 by optical system by camera lens proper communication The status information (step S2034) of " in driving " that control unit 211 sets.Then, the first adapter communications portion 312 obtains and passes through Camera lens proper communication and respond the status information (step S2036) of " in driving ".In addition, in step S2036, the first adaptation Device communication unit 312 only carries out the acquirement of the status information of " in driving ", does not send to the first camera communications portion 112.
Next, in the case of the movement of the target location to focusing lens 222 is completed, optical system control unit 211 control optical system drive divisions 230, make the driving of focusing lens 222 stop (step S3034).In addition, optical system controls According to the information making driving stop, the status information that the inside exchanging camera lens 200 is had is set as representing focusing lens in portion 211 222 driving condition is to drive halted state " drive and stop " (step S3036).
Then, the first camera lens communication unit 212 is responded in this step S3036 by optical system by camera lens proper communication The status information (step S2038) of " drive and stop " that control unit 211 sets.Then, the first adapter communications portion 312 obtains and leads to Cross camera lens proper communication and respond the status information (step S2040) of " drive and stop ".
First adapter communications portion 312 passes through normal data communication, will be set as the state information response of " drive and stop " To the first camera communications portion 112 (step S1040).First camera communications portion 112 is led to by the normal data of step S1040 Letter, to detect that status information is the situation (step S1045) of " drive and stop ".
So, the control instruction of the driving beginning to optical system drive division 230 is being sent out by the first adapter communications portion 312 After delivering to the first camera lens communication unit 212, it is not to wait for the response from the first camera lens communication unit 212, just the first photographing unit is led to Letter portion 112 sends the status information (expression is the status information in driving) representing driving condition.
In addition, in the case that the driving of optical system drive division 230 stops, the first adapter communications portion 312 is from One camera lens communication unit 212 obtains the response representing that optical system drive division 230 is in halted state, then the first photographing unit is led to Letter portion 112 sends the status information representing driving condition.
Thus, the first adapter communications portion 312 can reduce the timing having started to from the driving of optical system drive division 230 It is the time lag during the timing that the status information in driving is received by the first camera communications portion 112 to expression.
Thus, in the first camera communications portion 112, although can produce optical system drive division 230 is in driving Nor receive the period of the status information that expression is in driving.In addition, the driving stopping in optical system drive division 230 In the case of, after the first adapter communications portion 312 can be in halted state confirming driving, send status information to first Camera communications portion 112.
(camera lens start up process)
Then, camera lens start up process (process of step S100 of Fig. 8) is illustrated.
First, the summary of camera lens start up process is illustrated.

Adapter control unit 310 makes adaptor power supplies portion 320 generate the voltage of lens control system power supply Vc and supply and (supply Electricity) to exchange camera lens 200.Then, the first adapter communications portion 312, by the communication between the first camera lens communication unit 212, holds Determination processing installed by row camera lens, determines whether to be provided with exchange camera lens.In the case that exchange camera lens 200 is installed, the first mirror Head communication unit 212 sends lens drive system power supply Vp request signal (step S2140, step to the first adapter communications portion 312 S3140).Then, process is moved to camera lens initialization process (step S150) by adapter control unit 310.
Camera lens initialization process (step S150) is adapter 300 and the initialization process exchanging camera lens 200.
Adapter control unit 310 is receiving lens drive system power supply Vp request letter by the first adapter communications portion 312 In the case of number, adaptor power supplies portion 320 is made to generate the voltage of lens drive system power supply Vp and supply (power supply) and arrive exchange mirror 200.Then, the first adapter communications portion 312, by the communication between the first camera lens communication unit 212, executes camera lens initial Change processes (step S2150, step S3150).Here, lens drive system power supply Vp is not supplied to friendship from adapter 300 side The reasons why to change the foundation of camera lens 200 side be following.There is also and do not need the camera lens that power supply supply is carried out by exchange camera lens (for example, Manual focusing lens).Be provided with such exchange camera lens when, generate lens drive system power supply Vp and to carry out power supply supply dynamic Work can make adapter 300 side carry out unnecessary operation.Therefore, in the present embodiment, need not for not making adapter 300 carry out The operation wanted and the power supply order determining power supply.
Then, when adapter 300 and when exchanging the initialization of camera lens 200 and completing, the first camera communications portion 112 is from first Adapter communications portion 312 receive as represent initialize completed information " initialization completes ", using as to initialization true Accept one's fate the response results of order.Thus, photographing unit control unit 110 obtains initialization and completes information (step S1150).
When initialisation is completed, photographing unit control unit 110 is based in the camera body 100 of step S1120 and adapter 300 Between information exchange in obtain information, determine whether adapter 300 (step S1155) is installed.Step S1155 is sentenced It is set in the case of being not installed with adapter 300, photographing unit control unit 110 is judged to respect to camera body 100 not via suitable Orchestration 300 ground has been mounted directly conformance with standard camera lens (for example, exchanging camera lens 200A).On the other hand, judge in step S1155 In the case of being provided with adapter 300, photographing unit control unit 110 enters shot information and obtains (step S160) process.
Shot information obtains (step S160) and processes is to exchange camera lens with respect to the installation determination processing of adapter 300 and to take The process of the information of exchange camera lens 200 of adapter 300 must be installed on.Exchange camera lens 200 information be such as camera lens classification, The presence or absence of the presence or absence of the presence or absence of direct communication function, anti-vibration functions, electromagnetism aperture, the shot information such as open F value, focus information.
First camera communications portion 112 sends shot information to the first adapter communications portion 312 and obtains order, and reception is derived from The response of the shot information in the first adapter communications portion 312, obtains information (step S1160, the step exchanging camera lens 200 S2160).
Then, photographing unit control unit 110 is based on and obtains, in shot information, the shot information obtaining in (step S160), judges Exchange the species (classification) (step S1165) of camera lens 200.For example, photographing unit control unit 110 passes through to install determination processing (step S140 result of determination), to determine whether to be provided with CPU camera lens on adapter 300.
In the case of step S1165 being judged to be not installed with CPU camera lens, be judged to non-CPU camera lens installment state and Start, end is processed.
On the other hand, in the case of being judged to CPU camera lens is installed in step S1165, process is moved to lens function Start (step S170).
In addition, photographing unit control unit 110, based on the shot information obtaining, determines whether and for example has AF control (process) The camera lens of function, the camera lens of control (process) function (vibration Restrained Control function) with VR camera lens 223 or electromagnetism aperture-type camera lens.
The process that lens function starts (step S170) is based on the mirror that shot information obtains acquirement during (step S160) is processed Header, according to the classification (function) exchanging camera lens, carries out starting the process of respective function.First camera communications portion 112 Via the first adapter communications portion 312, communicated with the first camera lens communication unit 212, for example, carried out lens control chart Acquirement, direct communication permission settings, vibration Restrained Control start setting etc. and process (step S1170, step S2170, step S3170).
Then, photographing unit control unit 110 is judged to that CPU camera lens installment state starts, and end is processed.
So, adapter control unit 310 is according to the voltage from camera body 100 supply control system power Vcc 1 Dynamic, the voltage supply asking power system power supply PWR to camera body 100 starts.In addition, adapter control unit 310 according to from Camera body 100 supplies the voltage of power system power supply PWR, generates from power system power supply PWR to exchange camera lens 200 supply The voltage of lens control system power supply Vc.In addition, adapter control unit 310 is by supplying lens control to exchange camera lens 200 The voltage of system power supply Vc and from exchange camera lens 200 ask lens drive system power supply Vp voltage supply in the case of, from work( Rate system power supply PWR generates the voltage of lens drive system power supply Vp and is supplied to exchange camera lens 200.
Thus, adapter control unit 310 can be generated to exchange camera lens 200 based on the voltage supplying from camera body 100 The voltage of supply, and can suitably control the voltage of respective power-supply system to supply beginning timing.
In addition, adapter control unit 310 can differentiate the specification exchanging camera lens 200 in camera lens start up process, based on sentencing The specification being clipped to, to exchange camera lens 200 service voltage.In addition, the exchange camera lens that adapter control unit 310 can be arrived based on differentiation Specification, do not need voltage supply exchange camera lens in the case of, make to exchange camera lens voltage supply stop.
(initialization process of camera lens start up process detailed)
Then, using Figure 13 to using Figure 12 it is stated that the process of initialization (step S130) of camera lens start up process enter Row describes in detail.
Figure 13 is the figure representing one of the processing sequence of initialization process of camera lens start up process example.In fig. 13, with It is marked with same symbol, the description thereof will be omitted in the corresponding process of each process of Figure 12.
First camera communications portion 112, will be initial after the voltage (step S1130) of supply power system power supply PWR Change execution order and be sent to the first adapter communications portion 312 (step S1140), using as initialization requests.Thereafter, the first photograph The initialization completing to be detected being used for the initialization process to adapter 300 is completed to confirm order (step by machine communication unit 112 Rapid S1145a, S1145b, S1145c) repeat to be sent to the first adapter communications portion 312, wait from the first adaptation The response (step S1145) of " initialization completes " of device communication unit 312.
For example, the first camera communications portion 112 until obtain " initialization completes " response period (or, for adopting The period predetermined with timeout treatment), repeatedly initialization is sent to the first adapter communications portion 312 with cycle T s and complete to confirm Order.This initialization complete confirm order communication cycle Ts be Billy with Fig. 9 it is stated that normal data communication cycle T m Short time interval.That is, the first adapter communications portion 312, with the short time interval of cycle T m than normal data communication, compares Camera control portion 110 execution represents that the transmission processe of the whether completed information of initialization process (completes to confirm life to initialization The response of order is processed).That is, whether initialization process is completed confirms by photographing unit control unit 110 with than normal data communication The short time interval of cycle T m detecting.So, by accelerating to confirm the interval (cycle) that initialization completes, as a result, The process that carries out after the completion of initialization can be started early, be capable of the time required for the rising of shortening device and system.
First adapter communications portion 312, until initializing the period completing, repeats to from the first camera communications portion 112 Send initialization complete confirm order, " in initialization " to be responded as init state, using as represent be initialize The information of undone state.
In addition, in the figure, the first camera communications portion 112 is by completing to confirm order to the initialization of step S1145n Response results, obtain " initialization completes " response.
Thus, the first camera communications portion 112 can be with the cycle of the fast time interval of the cycle than normal data communication Carry out the whether completed confirmation of initialization process of test adaptor 300.
Adapter control unit 310 received by the first adapter communications portion 312 initialization exectorial in the case of, enter The initialization process (step S2130) in each portion that row adapter 300 possesses.This is for example to control the adapter of adapter 300 Process that memorizer in portion 310 resets etc..Then, adapter control unit 310 controls aperture trace drive division 330, makes light Circle trace 350 moves to retreating position (step S2135).
Next, process is moved to camera lens by adapter control unit 310 installs determination processing (step S140).In this camera lens peace In dress determination processing, adapter control unit 310 makes adaptor power supplies portion 320 generate the voltage of lens control system power supply Vc first And supply (power supply) and arrive exchange camera lens 200 (step S2142).Then, the first adapter communications portion 312 is according to exchange camera lens The voltage of 200 supply (power supply) lens control system power supply Vc, based on whether from the first camera lens communication unit exchanging camera lens 200 212 have response, to detect whether to be provided with exchange camera lens 200, thus carry out installing judging (step S2144, step S3144).
For example, in the case of not responding to from the first camera lens communication unit 212, it is judged to that being in exchange camera lens 200 does not pacify It is loaded on the state (the non-installment state of camera lens) of adapter 300.
On the other hand, the first adapter communications portion 312, in the case of having response from the first camera lens communication unit 212, judges Exchange, for being in, the state that camera lens 200 is installed on adapter 300, between adapter 300 and exchange camera lens 200, enter row information The communication (step S2146, step S3146) exchanging.
In the communication that information between this adapter 300 and exchange camera lens 200 exchanges, for example, the first adapter communications Portion 312 and the first camera lens communication unit 212 carry out the communication of mutual recognition and verification order, are mutually distinguishable, are confirmed whether energy Enough normally communicate.In addition, the first adapter communications portion 312 obtains identification exchanges the shot information of species of camera lens 200, expression Exchange information of state of lens switch (for example, the switch of switching AF and MF (Manual Focus)) that camera lens 200 possesses etc..
In addition, the first camera lens communication unit 212 sends lens drive system power supply Vp request to the first adapter communications portion 312 Signal.Then, process is moved to camera lens initialization process (step S150) by adapter control unit 310.
In camera lens initialization process (step S150), first, adapter control unit 310 is by the first adapter communications portion In the case that 312 receive lens drive system power supply Vp request signal, adaptor power supplies portion 320 is made to generate lens drive system The voltage of power supply Vp and supply (power supply) arrive exchange camera lens 200 (step S2152).Then, the first adapter communications portion 312 will ask The camera lens initialization execution order asking the execution of camera lens initialization process is sent to the first camera lens communication unit 212 (step S2154). Lens control portion 210 received by the first camera lens communication unit 212 camera lens initialization exectorial in the case of, according to from the The camera lens initialization in one adapter communications portion 312 executes order, execution camera lens initialization process (step S3154).
This camera lens initialization process be the initialization in lens control portion 210, AF control (controls of focusing lens 222) just Beginningization, initialization of vibration Restrained Control (control of VR camera lens 223) etc. are processed.In addition, the situation in electromagnetism aperture mode CPU camera lens Under, in this camera lens initialization process, also execute the initialization process of electromagnetism the control of diaphragm.
In addition, after camera lens initialization process completes, the first adapter communications portion 312 starts and the first camera lens communication unit Camera lens proper communication (step S2156) between 212.
Then, adapter control unit 310 executes initialization driving (step S2158) of aperture trace 350.For example, fit Orchestration control unit 310 controls aperture trace drive division 330, and execution makes the position of aperture trace 350 move to predetermined rule Position the process put.In addition, adapter control unit 310 is according to such as control condition, the position of aperture trace 350 is made to move to Retreating position, release position or be stored in position of storage part etc..
Next, the execution with the initialization driving of the aperture trace 350 of step S2158 completes, the first adapter Communication unit 312 completes to confirm order (step S1145n) to the initialization from the first camera communications portion 112, and response is " initial Change and complete ", using as init state (step S2159).First camera communications portion 112 is by initial to step S1145n Change the response results completing to confirm order, obtain the response (step S1150) of " initialization completes ", then terminate to initialize.
So, adapter control unit 310 can execute order according to the initialization from the first camera communications portion 112, To execute the initialization in each portion that adapter 300 possesses, to judge and be installed on the friendship of adapter 300 to installing of adapter 300 Change the initialization of the state of camera lens 200.In addition, the first camera communications portion 112 can with than normal data communication cycle (on State cycle T m/ such as 16msec) cycle (such as 10msec) of fast time interval carrys out the initialization process of test adaptor 300 Whether completed confirmation.Thus, photographing unit control unit 110 can suitably whether test initialization be processed with fast timing Complete.
(initialization completes the example of response data)
In addition, as described in using Figure 13, adapter control unit 310 will exchange camera lens 200 to exchanging camera lens 200 and requesting The process of state initialization after, execution aperture trace 350 initialization drive (initialization process).In addition, adapter Control unit 310, after the camera lens initialization process of the state initialization by exchanging camera lens 200 completes, completes to take a picture with by first Corresponding initialization process is ordered in the initialization execution that machine communication unit 112 sends.That is, complete initially in adapter control unit 310 In the past, camera lens initialization process is complete for the process (also comprising the process of the movement to retreating position of aperture trace 350) changed Become.
Thus, adapter control unit 310 can be after camera lens initialization process completes, in the first camera communications portion 112 carry out initializing the response completing.
Figure 14 A and 14B is to represent to be responsive to initialize the init state completing to confirm order in order data communication One of data configuration example figure.
For example, being responsive to initialize the data completing to confirm the init state ordered in order data communication is 2 ratios Special data.And, in the data of 2 bits, the next 1 bit D10 (bit0～7) is to represent that being in response to initialization completes really Accept one's fate order data order data.For example, as shown in the drawing, as being used for being identified as being responsive to initialization completing to confirm life The order data of the data of order, the example being set to the next 1 bit D10 that the data of " 15H " (15H of hexadecimal number) represents Son.In addition, upper 1 bit D20 (bit8～15) is intended to the data of the init state of response.In this upper 1 bit D20, The whether completed labelling (aperture of initialization process representing the aperture trace 350 in adapter 300 is set with bit8 Trace initialization completes information).In addition, be set with bit9 representing the initial of the focusing lens 222 exchanging in camera lens 200 Change processes whether completed labelling (camera lens initialization completes information).In addition, expression is set with bit10 exchange camera lens The whether completed labelling of initialization process (camera lens initialization completes information) of the VR camera lens 223 in 200.In addition, bit11～ 15 is undefined, is invalid data area.
Figure 14 A is as the first camera communications portion 112 and is sent to the as initialization requests by initializing execution order One adapter communications portion 312 and the first adapter communications portion 312 set be responsive to initialize complete confirm order initial The data (data setting in step S2130 of Figure 13) of change state.That is, the first adapter communications portion 312 completes to initialization Confirm the data shown in command response Figure 14 A, using as representing the data being in the init state representing " in initialization ".
In addition, in this timing (step S2130 of Figure 13), the initialization process of focusing lens 222, VR camera lens 223 just Whole initialization process of the initialization process of beginningization process and aperture trace 350 does not complete and (will exchange the shape of camera lens 200 The initialized process of state does not complete).But, the first adapter communications portion 312 exchanges the initialization shape of camera lens 200 side with regard to representing Bit9～10 of state, set the labelling " 0 " representing that initialization process completes respectively.In its opposing party and in expression aperture trace The labelling " 1 " representing that initialization process does not complete is set on the bit8 of the data of 350 init state.That is, adapter 300 is not The state (state of progress of initialization process) of the initialization process of pipe exchange camera lens 200 side how, often would indicate that initialization The labelling " 0 " that completes completing is set in bit9～10.So, by constituting the initialization tag in adapter 300, even if inciting somebody to action Can not would indicate that the labelling that initialization completes exports the exchange camera lens of the pattern of adapter 300 and is installed on via adapter 300 In the case of camera body 100, also action will be led to stop (photographing unit system in the stage of above-mentioned initialization process order System), it may have the available this advantage of species exchanging camera lens can be expanded.
When camera lens initialization process (step S150 of Figure 13) completes, the aperture trace 350 of adapter 300 side Initialization process not yet complete.
Figure 14 B is in response to drive the initialization process of (step S2158 of Figure 13) in the initialization of aperture trace 350 The initialization setting when completing completes to confirm the data of the init state of order.In this moment (step S2158 of Figure 13), Generally, the initialization process (step S150 of Figure 13) of camera lens side completes.
When the initialization process of aperture trace 350 completes, the first adapter communications portion 312 is in init state data Bit8 on set represent the completed labelling of initialization process " 0 ".Thus, on bit8～10 of init state data all Set and represent the completed labelling of initialization process " 0 ".That is, the first adapter communications portion 312 completes to initialization to confirm order, Data shown in response diagram 14B, using the data as the init state representing " initialization completes ".
That is, represent that the whether completed initialization of initialization process completes packet and contains：Often represent camera lens initialization process (by exchanging the process of the state initialization of camera lens 200) whether the initialization of completed camera lens complete information (Figure 14 A's and 14B Bit9,10), represent initialization process (aperture trace initialization process) the whether completed information of aperture trace 350 (initialization of aperture trace completes information) (bit8 of Figure 14 A and 14B).
Then, camera lens initialization, to exchanging camera lens 200 instruction initialization, is completed by the first adapter communications portion 312 simultaneously The value of information is set as representing the value that initialization completes, and completes with aperture trace initialization process, by the beginning of aperture trace The value that beginningization completes information is set as representing the value that initialization completes.
That is, the state of progress of the process regardless of the state initialization by exchanging camera lens 200 for the adapter control unit 310, The value all camera lens initialization being completed information is set as representing the value that initialization completes.In addition, adapter control unit 310 is with light Circle trace initialization process completes, and the value that the initialization of aperture trace is completed information is set as representing what initialization completed Value, and complete information to photographing unit control unit 110 transmission initialization.
In addition, adapter control unit 310 completes the timing confirming order (just according to the initialization of photographing unit control unit 110 The detection timing that beginningization is processed), respond (transmission) initialization to photographing unit control unit 110 and complete information.
So, the completion timing of the initialization process in aperture trace 350 for the adapter control unit 310, would indicate that initial Change whether completed information (labelling) updates and is responsive to photographing unit control unit 110.
Thus, the timing that adapter control unit 310 can complete in the initialization process of aperture trace 350, would indicate that Also comprise to exchange the initialization completion statuses response of whole completed order of initialization of the initialization of camera lens 200 side To photographing unit control unit 110.
(initialization when conformance with standard camera lens is installed)
In addition, in the above-described embodiment, at the initialization being connected with respect to camera body 100 during adapter 300 Reason is illustrated, but is not limited to this.For example, during adnexa beyond being connected with adapter 300 with respect to camera body 100 Initialization process in, adnexa can also similarly by camera body 100 come test initialization process whether complete.For example, In the adnexa that can removably fix with respect to camera body 100, accessory control unit that adnexa possesses by with camera body The communication (communication in normal cycle) in the cycle of photographing unit control unit 110 that 100 possess is controlling.Initialization in this situation In process, this accessory control unit can also carry out indicating corresponding initialization process with the control from photographing unit control unit 110, And carry out coming whether test initialization is processed by photographing unit control unit 110 with the time interval than the cycle is short of the communication in cycle The process completing.
As an example, below, it is conformance with standard mirror to the adnexa that can removably fix with respect to camera body 100 The situation of head illustrates.
(for example, exchange being directly connected to conformance with standard camera lens with respect to camera body 100 not via adapter 300 ground Camera lens 200A) in the case of, in camera lens normal process, for example, the first camera lens communication unit 212A is (with above-mentioned accessory control unit The first camera lens communication unit 212A that corresponding lens control portion 210A possesses) between the first camera communications portion 112, with week Phase Tm execution normal data communication (with the first adapter communications portion 312 shown in Fig. 9 and the first camera communications portion 112 it Between same cycle T m of normal data communication, execute normal data communication).
In addition, in camera lens start up process, processing equally with the initialization requests of step S1140 shown in Figure 13, first Camera communications portion 112 sends initialization to the first camera lens communication unit 212A and executes order.That is, the first camera communications portion 112 Send initialization to the first camera lens communication unit 212A and execute order, to replace the first adapter communications portion 312.Thereafter, with step The initialization of S1145 completes to confirm to process equally, and initialization is completed to confirm order with cycle T s by the first camera communications portion 112 Repeat to be sent to the first camera lens communication unit 212A, wait the response of " initialization completes " from the first camera lens communication unit 212A.
In addition, lens control portion 210A is receiving the exectorial situation of initialization by the first camera lens communication unit 212A Under, execution exchanges the camera lens initialization process of camera lens 200A.Then, the camera lens initialization process with lens control portion 210A is complete Become, the first camera lens communication unit 212A response " initialization completes ".
So, photographing unit control unit 110 from initialization requests to initialization complete confirm process with respect to photograph In the case of body 100 is connected with the situation exchanging camera lens 200 and has been directly connected to exchange camera lens 200A via adapter 300 Any one in the case of, be all same process.
That is, the first camera lens communication unit 212A is with the short time interval comparison camera control of cycle T m than normal data communication Portion 110 execution represents that the transmission processe of the whether completed information of initialization process (completes to confirm the response of order to initialization Process).That is, in the case of being directly connected to respect to camera body 100 exchange camera lens 200A, whether initialization process The confirmation completing also to be detected with the short time interval of cycle T m than normal data communication by photographing unit control unit 110.
Thus, the first camera communications portion 112 can be with the cycle of the fast time interval of the cycle than normal data communication To detect the whether completed confirmation of initialization process exchanging camera lens 200A.Thus, photographing unit control unit 110 can be with fast Suitably whether test initialization process completes for timing.
(power supply disconnection process and low consumpting power are processed)
Then, power supply disconnection process and low consumpting power are processed and illustrate.
Here, it is that the operating state (action pattern) of camera body 100 is transitioned into power consumption that low consumpting power is processed (second moves lower than the action pattern (the first action pattern) that can the carry out photograph processing action pattern that can not carry out photograph processing Operation mode/low consumpting power pattern/sleep pattern) process.
Here, in following, low consumpting power being processed and is referred to as sleep process, will be processed and the action of transition by sleep State (action pattern) is referred to as sleep pattern.
For example, the interrupt requests that the power supply according to camera body 100 disconnects, execute power supply disconnection process.In addition, no grasping Make to continue in situation more than stipulated time etc., execution sleep is processed.
In addition, power supply disconnection process and sleep process the function stop (pass comprising to make adapter 300 and exchange camera lens 200 Machine) and make the voltage of the power system power supply PWR from camera body 100 supply the camera lens shutdown process stopping (disconnection).That is, Power supply disconnection process and sleep process the voltage being to be fed into exchange camera lens 200 and stop and make the electricity of power system power supply PWR Pressure supply stops the process of (disconnection).
In addition, in the case that the action pattern of camera body 100 is to sleep mode transitions, stopping from camera body 100 The voltage supply of power system power supply PWR, the voltage supply of Sustainable Control system power supply Vcc1.For example, in camera body 100 Action pattern in the case of sleep mode transitions, by the control system power Vcc 1 of camera body 100 persistently predetermined period Voltage supply.Here, predetermined period for example is by detecting that the operation to camera body 100 to return to and can photograph The action pattern that processes and period of specifying or continuing further no in the case of mode of operation as transferring to camera body 100 Power supply disconnection process and period of specifying etc..
In addition, in the case that the action pattern of camera body 100 is to sleep mode transitions, representing and disconnect shape to power supply The indication signal (shutdown executes order) that the transition of state or sleep pattern is indicated is sent to suitable from photographing unit control unit 110 Orchestration control unit 310, with receiving this indication signal, execution will stop adapter control unit 310 to the power supply exchanging camera lens 200 Camera lens shutdown process.
Then, adapter control unit 310, in the case that camera lens shutdown process terminates, would indicate that license disconnects to power supply The enabling signal (response that shutdown is ready to complete) of state or sleep mode transitions is sent to camera body 100.Next, according to The enabling signal sending from adapter control unit 310, stops the voltage supply of power system power supply PWR from camera body 100.
Figure 15 is the figure representing one of the processing sequence of power supply disconnection process and sleep process example.
With reference to this figure, the power supply disconnection process of camera arrangement 1 and sleep are processed and illustrate.
Power supply disconnection process and sleep process and terminate (step S410), shutdown (step S420), sleep according to lens function The order of mode shifts (step S430) is processed.In addition, in this power supply disconnection process and sleep are processed, camera body 100 communications carrying out with exchange camera lens 200 via adapter 300 are that order data communicates.
When power supply disconnection process or sleep are processed when starting, carry out the process that lens function terminates (step S410) first.
First camera communications portion 112 is by entering with the first camera lens communication unit 212 via the first adapter communications portion 312 Row communication, makes the function action of exchange camera lens 200 stop (step S1210, step S2210, step S3210).Thus, camera lens control The function action exchanging camera lens 200 is stopped by portion 210 processed.For example, the process being terminated by lens function, swaps camera lens The forbidding etc. of the end of 200 vibration Restrained Control or direct communication is processed.
Then, shut down the process of (step S420).
Execution order of shutting down is sent to the first adapter communications portion 312 by the first camera communications portion 112, using as shutdown Request (step S1220).Thereafter, the first camera communications portion 112 repeat send shutdown complete confirm order, wait be derived from first The response that the shutdown in adapter communications portion 312 is ready to complete.
Adapter control unit 310 received by the first adapter communications portion 312 shutdown exectorial in the case of, start Camera lens shutdown is processed.First, the first adapter communications portion 312 will indicate to can not powering of lens drive system power supply Vp Order be sent to the first camera lens communication unit 212.Receive this order, lens control portion 210 with by the first camera lens communication unit 212 Voltage supply (power supply) of the lens drive system power supply Vp in exchange camera lens 200 is made to stop (step S3220).Then, first Camera lens proper communication with the first camera lens communication unit 212 is stopped by adapter communications portion 312.Then, adapter control unit 310 makes The voltage supply of the lens drive system power supply Vp from adaptor power supplies portion 320 stops, next, making lens control system electricity The supply of source Vc stops (step S2220).
Then, adapter control unit 310 makes aperture trace 350 move to retreating position (step S2230), executes adaptation The shutdown in each portion that device 300 possesses processes (step S2235).Next, the first adapter communications portion 312 is complete in shutdown process In the case of one-tenth, the shutdown according to receiving from the first camera communications portion 112 completes to confirm order, by " shutdown is ready to complete " It is responsive to the first camera communications portion 112, using as representing at the shutdown of adapter 300 (adapter 300 and exchange camera lens 200) Manage completed information.In addition, the presence or absence of process request of sleeping is responsive to the first photographing unit by the first adapter communications portion 312 leading to Letter portion 112 (step S2240).
First camera communications portion 112 obtains the response (step of " shutdown is ready to complete " from the first adapter communications portion 312 S1240), to complete to confirm the response results of order as shutdown.
Photographing unit control unit 110 is being obtained the situation of the response that shutdown is ready to complete by the first adapter communications portion 312 Under, 125 will be switched and control to off-state, and so that the voltage of power system power supply PWR is supplied and stop (step S1250).
Then, photographing unit control unit 110 judges to complete to confirm that having or not sleep pattern in the response results ordered turns in shutdown Move request (step S1255).Step S1255 is judged to no in the case of sleep pattern transfer request, photographing unit control unit 110 control camera power source portions 120, make the voltage of control system power Vcc 1 supply and stop (step S1270).
On the other hand, in the case that step S1255 is judged to there is sleep pattern transfer request, carry out sleep pattern transfer The process of (step S430).First, the first camera communications portion 112 will be sent to the first adaptation to the instruction of sleep mode transitions Device communication unit 312.Thus, adapter control unit 310 is to sleep mode transitions.For example, the first adapter communications portion 312 is to sleeping Before the process of sleep mode transition starts, signal RDY is controlled to H (high) level, completes to the process of sleep mode transitions After, signal RDY is controlled to L (low) level.First camera communications portion 112 is by under the signal level to signal RDY Fall edge is detected, carrys out the completed situation of the process to sleep mode transitions of test adaptor 300, by control system electricity The voltage supply of source Vcc1 is switched to little power supply state (step S1260, step S2260).
Thus, to power-off state or sleep mode transitions.
So, in the case that camera body 100 is transitioned into sleep pattern, photographing unit control unit 110 makes to adapter 300 Power system power supply PWR voltage supply stop, making control system power Vcc 1 voltage supply continue.That is, adapter 300 In the case of being transitioned into sleep pattern, stop the voltage supply of power system power supply PWR, Sustainable Control from camera body 100 The voltage supply of system power supply Vcc1.
Thus, can achieve low consumpting power in sleep pattern.In addition, will not Sustainable Control system power supply Vcc1 electricity Pressure supplies and makes the process of adapter control unit 310 stop (making adapter control unit 310 to recover to process required minimum completely Electric power carries out action).Therefore, adapter control unit 310 is when from sleep pattern to recovery (starting) of normal condition, and complete The situation stopping processing is compared, and can be recovered (starting) with the shorter time.
(process during power supply momentary interruption)
Power system power supply PWR, lens drive system power supply Vp, lens control system power supply Vc respectively provide regulation Voltage range.
By Vc voltage detection department 325, Vp voltage detection department 326 and PWR voltage detection department 327, to power system power supply The voltage of PWR, lens drive system power supply Vp and lens control system power supply Vc is detected, supplies to adapter control unit 310 To testing result.Adapter control unit 310 is in the power system power supply PWR detecting, lens drive system power supply Vp and camera lens In the case that any voltage in the voltage of control system power supply Vc is all low than the assigned voltage scope of regulation, by its testing result Camera body 100 is arrived in supply (notice).
For example, adapter control unit 310 is in the voltage (voltage of the power system power supply PWR powering from camera body 100 Value) and from adaptor power supplies portion 320 to exchange camera lens 200 power supply lens drive system power supply Vp voltage (magnitude of voltage) and from Adaptor power supplies portion 320 is to the arbitrary electricity in the voltage (magnitude of voltage) of the lens control system power supply Vc exchanging camera lens 200 power supply In the case that pressure (magnitude of voltage) is all low than the assigned voltage scope of regulation, in order to camera lens 200 (state) initialization will be exchanged, hold Row camera lens initialization process.
Specifically, the photographing unit control unit 110 that the camera body 100 making adapter control unit 310 is possessed is executed The initialization request signal that the initialization process comprising camera lens initialization process is indicated is from the first adapter communications portion 312 are sent to the first camera communications portion 112 and supply (notice) and arrive camera body 100.In addition, adapter control unit 310 exists Any voltage in the lens drive system power supply Vp detecting and the voltage of lens control system power supply Vc is all than the rule of regulation Determine voltage range low in the case of, make lens drive system power supply Vp and lens control system power supply Vc voltage supply stop, And initialization request signal is sent to camera body 100.
In addition, this initialization process is to supply temporarily in the voltage making power system power supply PWR according to initialization request signal When stop after starting again at the process of supply.In addition, this initialization process is to make control system according to initialization request signal The voltage supply of system power Vcc 1 starts again at the process of supply after temporarily ceasing.
In addition, adapter control unit 310 is according to the initialization process of camera body 100, make lens drive system power supply Vp And the voltage supply of lens control system power supply Vc starts.That is, adapter control unit 310 is according to the initialization of camera body 100 Process, so that lens control portion 210 is initialized.
That is, adapter control unit 310, in the case of supply voltage decline is detected, first, makes to exchange camera lens 200 Voltage supply stops.Then, adapter control unit 310 sends initialization request signal to photographing unit control unit 110, makes from photograph After the voltage supply of the power supply of body 100 supply temporarily ceases, execute the process being initially supplied again.Thus, by again Execution camera lens start up process, to carry out initialized process, and adapter control unit 310 is to exchange camera lens 200 service voltage.
Thus, adapter control unit 310 can be in power system power supply PWR, lens drive system power supply Vp and camera lens control In the case that any voltage in the voltage of system power supply Vc processed is all low than the assigned voltage scope of regulation, execute adapter 300 And exchange the initialization of camera lens 200.Therefore, it is possible to leading to persistently exchange camera lens 200 side under unstable power supply state The unfavorable condition of action prevents trouble before it happens.
In addition, the magnitude of voltage in power system power supply PWR, lens drive system power supply Vp and lens control system power supply Vc In it is also possible to good and bad (importance degree, relative importance value) on judging.From the point of view of stable power supply maintains this viewpoint, first, it is Generate service voltage and the magnitude of voltage of (powering to adaptor power supplies portion 320) of powering is necessary in prescribed limit. Otherwise, the magnitude of voltage generating thereafter is also possible to fluctuate.Thus, first determine whether whether the magnitude of voltage of power system power supply PWR has Abnormal.Secondly importantly, the execution of camera lens 200 side is correct to be controlled in order to exchange, need to be stably driven with lens control portion 210.Therefore, whether its secondary judgement has exception to the lens control system power supply Vc that lens control portion 210 powers.That is, as long as Each voltage is judged with power system power supply PWR, lens control system power supply Vc, this relative importance value of lens drive system power supply Vp Whether value has abnormal.So, by carrying quality on judging, for example, even if the electricity in lens drive system power supply Vp In the case of pressure value display exception, if the magnitude of voltage of lens control system power supply Vc is also normal and lens control portion 210 also just Normal ground action (normally execution communicates between adapter control unit 310), then do not make at the execution reset of exchange camera lens 200 side Reason (initialization process) is it is also possible to make it extensive with other fault processing (the driving/action again again of the driving factor of camera lens side) Multiple.Thereby, it is possible to prevent easy to do (unnecessary) initialization process.
Then, the example of process when declining as supply voltage, enters to process during power supply momentary interruption with reference to Figure 16 Row explanation.
Figure 16 is the figure of one of processing sequence when representing power supply momentary interruption example.
Under camera lens normal condition, the first camera communications portion 112 and the first adapter communications portion 312 are executed with cycle T m Normal data communication (step S1310, S1312, S1314).The adaptor power supplies control unit 311 of adapter control unit 310 is from Vc The testing result of voltage detection department 325, Vp voltage detection department 326 and PWR voltage detection department 327, to lens control system power supply State after the voltage of Vc, lens drive system power supply Vp and power system power supply PWR temporarily declines is detected (step S2310).Example shown in this Figure 16 is lens control system power supply Vc, lens drive system power supply Vp and power system power supply The example of while creating the momentary interruption of power supply () when the voltage of PWR recovers after temporarily declining again.Adaptor power supplies control unit 311 Detected according to the state (creating the state of the momentary interruption of power supply) after decline temporary transient to voltage, execute to exchange camera lens The disconnection process of the power supply of 200 supplies.For example, adaptor power supplies control unit 311 makes adaptor power supplies portion 320 according to lens driving System power supply Vp, the order execution of lens control system power supply Vc make voltage supply the control stopping, using the disconnection as power supply Process (step S2320).
Then, lens drive system power supply Vp and the electricity of lens control system power supply Vc are made by adaptor power supplies portion 320 After pressure supply stops, the first adapter communications portion 312 be would indicate that by normal data communication (step S1314) and power supply is detected The information response of momentary interruption is to the first camera communications portion 112 (step S2330).For example, the first adapter communications portion 312 will " having the initialization request signal of power supply momentary interruption detection " (initialization request signal) is sent to the first camera communications portion 112, using as representing signal power supply momentary interruption is detected.
Next, photographing unit control unit 110 " has power supply momentary interruption to examine with being received by the first camera communications portion 112 The initialization request signal surveyed ", will switch 125 and control to off-state, so that the voltage of power system power supply PWR is supplied and stop (step S1330).In addition, photographing unit control unit 110, after the voltage making power system power supply PWR supplies stopping, controlling and shines Camera power supply portion 120, makes the voltage of control system power Vcc 1 supply and stops (step S1340).
Next, photographing unit control unit 110 executes the process of camera lens start up process (step S100 of Fig. 8), then execute electricity The power supply of pressure and initialized process.
So, in the case of there occurs to the momentary interruption of the power supply exchanging camera lens 200 supply, adapter control unit 310 pairs of situations that there occurs momentary interruption detect, make to the voltage exchanging camera lens supply with from camera body 100 supply Voltage temporarily ceases, and makes power-off state, and thereafter, execution is restarted, and executes initialization process.Thus, even if sending out In the case of having given birth to the momentary interruption of power supply, adapter control unit 310 also can make adapter 300 and exchange camera lens 200 initial Change and be transitioned into normal operating state.
In the above-described embodiment, when adaptor power supplies control unit 311 is from Vc voltage detection department 325, Vp voltage detection department The testing result of 326 and PWR voltage detection departments 327 is to lens control system power supply Vc, lens drive system power supply Vp and power When state after the temporarily decline of the voltage of system power supply PWR is detected, by exchanging the power supply disconnection that camera lens 200 supplies, enter The initialization process of row camera lens.But, declined, by having carried out voltage, the feelings judging in the testing result of only Vp voltage detection department 326 Under condition (do not carried out voltage does not decline situation about judging to the testing result of Vc voltage detection department 325 and PWR voltage detection department 327), In itself being shown that normally to execute due to the communication between adapter control unit 310 and lens control portion 210, therefore can also Do not execute the initialization process exchanging camera lens 200.
In addition, in the above-described embodiment, to the testing result with power supply momentary interruption from adapter control unit 310 Deliver to initialized example (the adapter control of photographing unit control unit 110 and photographing unit control unit 110 execution exchange camera lens 200 Portion 310 is to ask to carry out initialized example in the form of the instruction of photographing unit control unit 110) it is illustrated, but not office It is limited to this.For example, adapter control unit 310 can not also ask the instruction from photographing unit control unit 110, but sentences at itself After the necessity of initialization execution of having broken, then exchange camera lens 200 is made to execute initialization.
In addition, in the present embodiment, carry out to possessing the whole composition of above three voltage detection department 325～327 Explanation.But, even only having any one of these three voltage detection departments or the composition of two, also can get and this enforcement The same effect of mode.In this case, particularly, as the position carrying out voltage detecting, effectively (preferential) position It is PWR voltage detection department 327, below as the priority in its effect face, be Vc voltage detection department 325, Vp voltage detection department 326 order.
The effect producing therefrom is as described above.
(information of identification information exchanges)
Then, the process that in camera arrangement 1, identification information is entered with row information exchange is illustrated.

For example, camera body 100 has the camera body identification information of the individuality of identification camera body 100 (hereinafter referred to as Camera body ID).In addition, exchange camera lens 200 has the camera lens identification information of the individuality of identification exchange camera lens 200 (hereinafter referred to as Camera lens ID).In addition, adapter 300 has adapter identification information (the hereinafter referred to as adapter of the individuality of identification adapter 300 ID).
Here, identification id is for example by the subsidiary intrinsic number (for example, manufacturing serial number) in each individuality during fabrication Etc. the identification information to represent, it is recognizable respective individual identification information.Thus, for instance, it is possible to by obtaining this identification ID is detecting function that name of product corresponding to identification id, product category, product carry, to manufacture record information etc..
In addition, the communication process that communicated by order data of these identification ids and receive and dispatch, exchanging camera lens 200, photographing unit Enter row information between body 100 and adapter 300 to exchange.
The process that in camera arrangement 1, identification id is entered with row information exchange is carried out as follows.
First, camera body ID is sent to the adapter control unit 310 of adapter 300 by camera body 100.Adapter control Portion 310 processed obtains the camera body ID sending from camera body 100.In addition, Adapter ID is sent to by adapter control unit 310 Camera body 100.Then, the camera body ID obtaining from camera body 100 is sent to exchange camera lens by adapter control unit 310 200.In addition, Adapter ID is sent to exchange camera lens 200 by adapter control unit 310.Next, adapter control unit 310 takes Obtain from exchanging the camera lens ID that camera lens 200 sends, the camera lens ID of acquirement is sent to camera body 100.
For example, the process these identification ids being swapped is in camera lens start up process (step S100 with reference to Fig. 8 and figure 12) carry out in.
Specifically, adapter control unit 310 is powered with from camera body 100, and Adapter ID is sent to photographing unit Body 100, and obtain the camera body ID sending from camera body 100.Thereafter, by the control instruction with camera body 100 In the execution of the initialization process of state initialization of corresponding exchange camera lens 200, camera body ID and Adapter ID are sent To exchange camera lens 200.Next, adapter control unit 310 is in the case of initialization process is completed, according to from photographing unit The request of body 100, camera lens ID is sent to camera body 100.
Figure 17 is that the information representing identification id exchanges the figure of one of the processing sequence processing example.
Information with reference to the identification id to camera lens start up process for this figure exchanges being described in detail of process.
In addition, what Figure 17 represented is the information being identified ID in the processing sequence of camera lens start up process shown in Figure 12 The process of the process exchanging.In fig. 17, process corresponding with each process of Figure 12 is marked with same symbol, omits it and say Bright.
Adapter control unit 310, with the electric power from camera body 100 supply control system power Vcc 1, carries out dismounting and sentences The process of fixed (step S110), enters the process that the information between camera body 100 and adapter 300 exchanges (step S120).
Information between camera body 100 and adapter 300 exchanges in (step S120), as described in using Figure 12, the One camera communications portion 112 is communicated with the first adapter communications portion 312 establishment of (order data communication).Then, first Camera communications portion 112 and the first adapter communications portion 312 to obtain camera body 100 and adapter 300 by being in communication with each other Respective identification id, title, the information such as firmware version.
In managing in this place, camera body ID is sent to the first adapter communications portion 312 by the first camera communications portion 112. In addition, Adapter ID is sent to the first camera communications portion 112 by the first adapter communications portion 312.Thus, the first photographing unit leads to Letter portion 112 obtains the Adapter ID sending from the first adapter communications portion 312.In addition, the first adapter communications portion 312 obtain from The camera body ID (step S1120, step S2120) that first camera communications portion 112 sends.
Then, in the process of initialization (step S130), initialization is executed order by the first camera communications portion 112 (control instruction) is sent to the first adapter communications portion 312, using as initialization requests (step S1140).According to this initialization Execute order, execution will exchange the process of the state initialization of camera lens 200.
In the initialized process of step S130, the first adapter communications portion 312 and the first camera lens communication unit 212 are carried out The process that the information of identification id exchanges.Specifically, enter the logical of row information exchange between adapter 300 and exchange camera lens 200 In the process (step S2146, step S3146) of letter, camera body ID and Adapter ID are sent by the first adapter communications portion 312 To the first camera lens communication unit 212, camera lens ID is sent to the first adapter communications portion 312 by the first camera lens communication unit 212.
Thus, the first camera lens communication unit 212 obtains the camera body ID sending from the first adapter communications portion 312 and adaptation Device ID.In addition, the first adapter communications portion 312 obtains the camera lens ID sending from the first camera lens communication unit 212.
Next, in the case of the process of initialization (step S130) is completed, obtaining (step in shot information S160, in process), the first camera communications portion 112 sends shot information to the first adapter communications portion 312 and obtains order.So Afterwards, the first camera communications portion 112 receives the response of the shot information from the first adapter communications portion 312, obtains and exchanges mirror 200 information.In managing in this place, the first camera communications portion 112 obtains from the first camera lens from the first adapter communications portion 312 The camera lens ID (step S1160, step S2160) of the exchange camera lens 200 that communication unit 212 sends.
So, adapter 300 sends Adapter ID to exchanging camera lens 200, and sends the camera body of camera body 100 ID.That is, exchange camera lens 200 and not only obtain Adapter ID, and obtain camera body ID.
Thus, exchange the individuality that camera lens 200 is capable of the specific camera body 100 connecting via adapter 300.
Thus, exchange camera lens 200 and can be based on camera body ID, to carry out corresponding to each individuality of camera body 100 Process.For example, exchange camera lens 200 can be based on camera body ID, via adapter 300, carry out to camera body 100 The license of process, the process of limitation function or connecting moves that process content is changed and objectionable process etc..In addition, i.e. Make, in the case that the mutually different camera body of communication standard 100 and exchange camera lens 200 connect via adapter 300, to hand over Change camera lens 200 and also can send and be converted to count corresponding with the species of the camera body 100 detecting based on camera body ID Data according to form.In addition, exchange camera lens 200 also only can be manufactured to the period in regulation based on the camera body ID obtaining Camera body 100 individuality, the process being specified (for example, regulation period manufacture individuality on there is process not In the case of good situation, only the individuality with its unfavorable condition is eliminated and process as its unfavorable condition).
In addition, camera body 100, exchange camera lens 200 and adapter 300 obtain in camera lens start up process respectively respective Identification id.Therefore, camera body 100, exchange camera lens 200 and adapter 300 can be carried out based on the device being connected The process of identification id.Thus, for example, in the communication standard camera body different from existing device, camera lens or adapter are exchanged In the case of connection, in these communication standards camera body different from existing device, exchange in camera lens and adapter, can Enough make the composition carrying out process corresponding with existing device.
In addition, exchange camera lens 200 can be processed based on the combination of the camera body ID obtaining and Adapter ID.With Sample, photographing unit control unit 100 can be processed based on the combination of the Adapter ID obtaining and camera lens ID.In addition, same, adaptation Device 300 can be processed based on the combination of the camera body ID obtaining and camera lens ID.
Thus, even the exchange camera lens 200 of mutually different communication standard and camera body 100 are it is also possible to pass through warp Connected by adapter 300, carry out suitably function.
The data processing ＞ of ＜ order data communication
Then, in the first data communication system D1b using mutually different communication standard and the first data communication system It is to take communication data and communications command that system D1L carries out the first adapter communications portion 312 in the order data communication of communication process The matching of form and the data processing that carries out illustrate.
(composition in the first adapter communications portion 312)

The shot information (the first shot information) that this 5 class can be divided into is respectively directed to those each information (species), with regard to Whether it is will to be intended to if will to information that camera body 100 send change to the information that camera body 100 sends and then then Why the data of sample and the information that sends, (specifically, those each information (species) are all predefined with suitable to be predefined with order Sequence, its order is as described above, the nonvolatile memory that is all stored in adapter control unit 310).Adapter control unit 310 According to its predetermined order, determine the presence or absence of transmission to camera body 100 and the conversion method of data to be sent, then hold Row transmission processe.
For example, define whether with corresponding respectively to its information (classification, species) will be to camera body 100 for the first shot information Send.Its benchmark judging if the information (species) asked from camera body 100, is then judged as information to be sent, no Then, it is judged as the information not needing to send.Then, the first adapter communications portion 312 is based in the first shot information and is defined as The information (information corresponding with above-mentioned classification 1～4) to send to camera body 100, (body sends to generate the second shot information With shot information).
In addition, the first adapter communications portion 312 is by carrying out corresponding to its shot information (classification) to the first shot information Conversion process, generate the second shot information (body transmission shot information).
For example, the first shot information, in the case of generating as the second shot information, (is planted corresponding to shot information Class) define whether conversion process to be carried out (its order).Then, the first adapter communications portion 312 is by believing to the first camera lens The information being defined as " carrying out conversion process " in breath carries out conversion process, generates the second shot information.In addition, the first adapter leads to Letter portion 312 pass through be not defined as in the first shot information " do not carry out conversion process (in other words, carry out conversion coefficient be 1 turn Change process) " the first shot information carry out conversion process, using the intact information of the first shot information as the second camera lens Information and generate.In addition, with regard to this judgment standard and conversion process, followed by description.
In addition, the first adapter communications portion 312 is to the information that can not obtain from exchange camera lens 200 in the second shot information, As the second shot information, (body sends the information information of pre-preparation as information to be sent being replaced this can not obtain With shot information) and generate.
Then, the detailed of the data processing to shot information to be described with reference to Figure 19 and Figure 20.
Figure 19 is the flow chart representing to one of the data processing of shot information obtaining example.
First, the first adapter communications portion 312 obtains the first camera lens from the first camera lens communication unit 212 exchanging camera lens 200 Information (step S510).
For example, data selecting section 312a is from being lens data by exchanging the first shot information of obtaining of camera lens 200, based on the The species of one shot information, selects process object lens data, then the lens data chosen is supplied to data processing division 312b.
Then, data processing division 312b carries out data processing (step to the lens data chosen by data selecting section 312a Rapid S520).
Next, data generating section 312c is from the lens data being performed data processing by data processing division 312b, generate The lens data (step S530) sending to the first camera communications portion 112 of camera body 100.For example, data generating section 312c will be performed the lens data of data processing by data processing division 312b, makes and sends to the first camera communications portion 112 Lens data the corresponding data arrangement of form, generate transmission lens data (body transmission shot information).
Figure 20 is the flow chart of one of the in detail example of the data processing of step S520 representing Figure 19.
The data processing of step S520 has process 1 (step S521), processes 2 (steps S522), processes 3 (steps S523), 4 (steps S524) are processed.Expression will carry out processing the order (letter of judgment standard of which kind of process in 1～process 4 Breath) it is directed to each shot information (species), all prestore the nonvolatile memory being stored in adapter control unit 310.Adapter The order (information) based on this storage for the control unit 310, for each shot information (species), all carries out predetermined place described later Reason.
Data selecting section 312a is lens data from the first shot information being obtained by exchange camera lens 200, based on each camera lens Information (species), is selected to the camera lens letter of the above-mentioned object of respective process (process 1, process 2, process 3 or process 4) Breath.Then, each shot information chosen is supplied to data processing division 312b by data selecting section 312a.Data processing division 312b Respectively to each shot information chosen by data selecting section 312a, the place of execution regulation corresponding to each shot information (species) Reason.
The process 1 of step S521 is not carry out conversion process etc. to the lens data obtaining, but directly using acquirement The process (in other words, implementing the process of the conversion of " conversion coefficient=1 ") of lens data.
For example, in this place in reason 1, processed shot information is as because from the first camera lens exchanging camera lens 200 acquirement The identical mirror without data conversion of respective data form of information and the second shot information sending to camera body 100 Header and predetermined shot information.
Processing in 1, data processing division 312b is to as the shot information not needing conversion, corresponding shot information sets For intact data, terminate data processing.As this shot information, comprise for example to illustrate as above-mentioned classification 1 Shot information.That is, exit pupil position information is as the shot information not needing conversion process, in advance in adapter control unit 310 Interior imparting defines.
That is, it is camera body 100 and the information exchanging camera lens 200 both sides all uses in shot information, and number between the two In the case of defining identical, adapter control unit 310, directly using the first shot information receiving, prepares the second camera lens letter Breath (body transmission shot information).
The process 2 of step S522 is the process that the lens data obtaining is carried out with the regulation corresponding to shot information (species) Process.
For example, in this place in reason 2, processed lens data is as because from the first camera lens exchanging camera lens 200 acquirement The respective data form of information and the second shot information sending to camera body 100 is different and need data conversion Lens data and (containing its order in nonvolatile memory internal memory) shot information of adapter control unit 310 pre-identification.Make For this shot information, there is the shot information for example illustrating as above-mentioned classification 2.That is, open F value information and image planes are moved Momentum corrected parameter, as the shot information needing data conversion treatment, gives definition in advance in adapter control unit 310.
In addition, processing the process that 2 data conversion treatment corresponds to each shot information (classification) and specifies, it is by first The lens data of shot information is converted to the process of the corresponding lens data of data form of the second shot information.For example, 2 are processed Data conversion treatment be the process of the data form being 2 bits by the Data Format Transform of 1 bit, to data execution by changing The translation operation of expression such as formula (functional expression) and process of changing etc..
Processing in 2, data processing division 312b, to the shot information being defined as the shot information (species) needing conversion, holds The predetermined above-mentioned process 2 of row, terminates data processing.
That is, it is camera body 100 and the information exchanging camera lens 200 both sides all uses in shot information, and number between the two In the case of definition difference, adapter control unit 310, to the first shot information receiving, implements the conversion process of regulation, Prepare the second shot information (body transmission shot information).
The process 3 of step S523 is the process that the lens data of acquirement is not sent to camera body 100.
As execution process 3 shot information, for example, from exchange camera lens 200 obtain shot information not as photographing unit The necessary information in body 100 side and define and (in other words, as the request object of the request command of camera body 100 side, do not comprise this Shot information), the lens data of this acquirement, for camera body 100, is unwanted camera lens number as the second shot information According to.
Processing in 3, data processing division 312b is to default in adapter control unit 310 as unwanted lens data The shot information (species) of justice, execution is made and does not need the process of the lens data as the second shot information (to be formed in data Generating unit 312c generates the process of the lens data not used during transmission lens data), then terminate data processing.As this Plant lens data (the first shot information), there is the shot information for example illustrating as above-mentioned classification 5.That is, represent shaft coupling The information of the relation between device rotation amount and image planes amount of movement as do not need to (due to not asking from camera body 100) photograph The shot information that body 100 sends, gives definition in advance in adapter control unit 310.
That is, in the case that shot information is not the information that camera body 100 uses, adapter control unit 310 will not be right Should prepare as the second shot information (body transmission shot information) in the information of this shot information.
The process 4 of step S524 is can not be from lens data to the second shot information sending to camera body 100 Exchange camera lens 200 obtain lens data set up in adapter control unit 310 information (fixed value data) of pre-preparation right The process answered.In other words, processing 4 is to apply the process of the fixed value data of regulation as the second shot information.Manage 4 in this place In, by data class, it is further divided into two kinds of process.First, the first process is illustrated.
For example, in this place in reason 4, processed lens data is not from the first camera lens letter exchanging camera lens 200 acquirement Comprising in breath will be to the lens data of the second shot information of camera body 100 transmission.
For example, camera body 100 possess by image procossing to exchange camera lens 200 in optical system produce be used as figure The unfavorable condition of picture is modified the function of processing, and the second shot information to be obtained comprises the optical system of this image procossing use The lens data that system is revised.On the other hand, exchange the lens data that camera lens 200 does not have this optical system correction.That is, should The lens data of optical system correction is included in the second shot information that adapter 300 sends to camera body 100 and (changes speech It, the shot information of camera body 100 request) in, but be not included in from the shot information exchanging camera lens 200 acquirement (in other words, From adapter 300 to the shot information exchanging camera lens 200 request) in.In this case, data processing division 312b is processing 4 Data conversion treatment in, for example enter to be about to default in and (be stored in the non-of adapter control unit 310 in such as adapter 300 In volatile memory) the optics correction data that the specifies (stated number using as controlling with camera body 100 According to) it is set as the process of Surrogate data for being responsive to camera body 100.The optics correction data of this regulation is no matter to pacify Exchange camera lens equipped with which kind of pattern also sends the same correction data of identical value to camera body 100 side.In addition, conduct The optics correction data of regulation, for example, it is also possible to as the correction effect that will be capable of specifying in camera body 100 Data setting is the optics correction data of regulation, or it is also possible to is data setting as zero for specifying by correction effect Correction data.
So, as processing 4, the correction data of alternative regulation, as the shot information being set process, has for example The shot information illustrating as above-mentioned classification 3.That is, multiplying power chromatic aberration information and spectral-transmission favtor information be prestore be stored in suitable Regulation data in orchestration 300 is sent to the shot information of camera body 100 as the data corresponding to those data, in advance Definition is given in adapter control unit 310.
That is, it is not to exchange the information that camera lens 200 uses in shot information, and with to exchange in the combining of camera lens 200 be to shine In the case of the information that camera body 100 uses, adapter control unit 310 prepares to prestore the control being stored in adapter control unit 310 The regulation data of system, using as the second shot information (body transmission shot information).
Then, illustrate to processing as the second processing 4.Data processing division 312b is in the data conversion processing 4 In process, as setting processing corresponding with shot information (species), carry out setting on camera body 100 and be judged to invalid number According to data process.In the process 4 of adapter control unit 310, it is fixed value data in the data setting representing engineering noise, And in the case of sending it to camera body 100 side, in camera body 100 side receiving this data, its data not as The data that initially there are, carries out the process of later camera body 100 side.So, as processing 4, as engineering noise will be defined Information setting be processed as the shot information of fixed value data, there is the shot information for example illustrating as above-mentioned classification 4. That is, peripheral light amount (dim light) information is to prestore to be stored in represent invalid " fixed value data " as corresponding in adapter 300 The data of its information is sent to the shot information of camera body 100, gives definition in advance in adapter control unit 310.This Sample, data processing division 312b is being processed in 4, and to the shot information (species) that can not obtain from exchange camera lens 200, execution is corresponding Set the process of fixed value data, then terminate data processing.
That is, it is not to exchange the information that camera lens 200 uses in shot information, and with exchanging in the combining of camera lens 200 be not In the case of the information that camera body 100 uses, adapter control unit 310 prepares to represent the stated number that this shot information is invalid According to using as the second shot information (body transmission shot information).
As described above, the first adapter communications portion 312 is based on from shot information (the first camera lens exchanging camera lens 200 acquirement Information), by carrying out respectively being suitable for the process of shot information (species), generate the shot information (machine sending to camera body 100 Body transmission shot information).For example, the first adapter communications portion 312 (plants based on from the shot information exchanging camera lens 200 acquirement Class), carry out the process of intact information making the information of acquirement, the process that the information obtaining is changed, make In the process of the information information of acquirement not sent or the process to the information setting generation fixed value data that can not obtain Arbitrary process, generates the shot information (body transmission shot information, the second shot information) sending to camera body 100.
Thus, adapter 300 can be between the exchange camera lens 200 of mutually different communication standard and camera body 100 Communication relayed, and can according to above-mentioned shot information (species) by exchange camera lens 200 information be appropriately converted to The information sending to camera body 100.That is, adapter 300 can according to the information (species) of connected exchange camera lens 200, Appropriately generate the shot information of the exchange camera lens 200 sending to camera body 100.Thus, even mutually different communication The exchange camera lens 200 of standard and camera body 100 are it is also possible to by connecting via adapter 300, suitably to play work( Energy.
In addition, the first adapter communications portion 312 can also generate the second shot information (machine according to the species exchanging camera lens Body transmission shot information).That is, the first adapter communications portion 312 can also be with mutual not phase corresponding with the species exchanging camera lens Same method, generates the second shot information (body transmission shot information).
For example, the first adapter communications portion 312 can also select to first receiving according to the species exchanging camera lens Shot information is implemented the conversion process of regulation and is generated (preparation) second shot information (body transmission shot information) and by advance It is stored in the regulation data (information for example, specifying controlling in adapter control unit corresponding to shot information (species) (fixed value data)) generate any one in (preparation) as the second shot information.
Here, the species exchanging camera lens is such as CPU camera lens or non-CPU camera lens etc..
That is, the first adapter communications portion 312 can also be connected with CPU camera lens or connection according to respect to adapter 300 There is non-CPU camera lens, generate the second shot information.For example, the first adapter communications portion 312 can under being connected with CPU camera lens state In the first shot information obtaining, have and become the information that cannot obtain during the state being connected with non-CPU camera lens.Therefore, One adapter communications portion 312 according to being connected with CPU camera lens or can also be connected with non-CPU camera lens, to select the first camera lens is believed Information (the fixed value that breath carries out conversion process and generates the second shot information and make the regulation corresponding to shot information (species) Data) generate any one of second shot information (body transmission shot information).
Here, the first adapter communications portion 312 powers with to exchange camera lens 200, according to whether having from exchanging camera lens 200 Response, to judge being CPU camera lens or non-CPU camera lens.In addition, the first adapter communications portion 312 can also be according to whether from friendship Change camera lens 200 and achieve the first shot information, to judge being CPU camera lens or non-CPU camera lens.
In addition, the first adapter communications portion 312 can also be according to being camera lens or the electromagnetism aperture being equipped with vibration proof mechanism The camera lens of formula, to select to carry out conversion process to the first shot information and to generate the second shot information and make corresponding to camera lens letter The information (fixed value data) ceasing (species) and specifying generates any one in the second shot information.
In addition, the adapter 300 based on step S160 shown in Figure 12 for the first adapter communications portion 312 and exchange camera lens The first shot information obtaining in the process that information between 200 exchanges, to judge to be equipped with the camera lens of vibration proof mechanism or Camera lens of electromagnetism aperture-type etc..
Thus, adapter 300 can appropriately generate to camera body according to the species of the exchange camera lens 200 installed The shot information of the exchange camera lens 200 of 100 transmissions.In addition, by by the exchange camera lens of mutually different communication standard (for example, Exchange camera lens 200A, 200B, 200C etc.) and camera body 100 connect via adapter 300, various optical systems can be made 220 suitably function.
(generation of communication data (camera lens name data) is processed)
Then, to giving birth in adapter 300 exchanging in the case that camera lens 200 does not have the information of expressions " camera lens title " The process becoming camera lens name data illustrates.
First adapter communications portion 312 can be generated based on the information (the first shot information) exchanging camera lens 200 obtaining Represent the information of " title " of exchange camera lens 200 that be installed on adapter 300.For example, the first adapter communications portion 312 be based on from The expression that the first shot information that exchange camera lens 200 obtains comprises exchanges the information (specification information) of the feature of camera lens 200, generates Represent the information of " title " of exchange camera lens 200 that be installed on adapter 300.
For example, title and the table of camera lens are exchanged in advance known to the nonvolatile memory memory storage in adapter 300 Show that it exchanges the specification information (optical characteristics information and function information) of the feature of camera lens, using as imparting corresponding corresponding letter Breath (hereinafter referred to as " the first corresponding informance (the first chart-information) ").Then, the first adapter communications portion 312 be based on its first Chart-information and from actual installation in adapter 300 exchange camera lens 200 obtain optical system 220 specification information (optics The characteristic information such as characteristic information and function information), select (presumption) to have closest to actual acquirement from the first chart-information The title of the camera lens of the specification information of specification information, using the title as the exchange camera lens 200 being installed on adapter 300.Thus, The information based on the title representing the camera lens chosen from its first chart-information for the first adapter communications portion 312, generates table Show the information of " title " that exchange camera lens 200.With regard to this generation method, it is described in detail below with Figure 21～22.
Figure 21 is the flow chart representing one of the process of generation camera lens name data example.
First, the first adapter communications portion 312 obtains from the first camera lens communication unit 212 exchanging camera lens 200 and exchanges camera lens 200 information (step S540).In this step S540, while the information of this exchange camera lens 200 obtains, also obtain from it Shot information in, the information carrying out generation for camera lens name data selects.
For example, the selection benchmark based on regulation for the data selecting section 312a (Figure 18), from the exchange exchanging camera lens 200 acquirement In the information of camera lens 200, it is chosen as the information category (class that selection generates the information of title representing exchange camera lens 200 and needs Not).The selection benchmark pre-defined of this regulation is in adapter control unit 310.In the present embodiment, to being installed on adapter The information that main " specification " (optical characteristics information and function information) of 300 exchange camera lens 200 is related is selected.If For its " specification " an example it is simply that below its with Figure 22 description exchange the focal length of camera lens 200, open F value, light ring manipulation The presence or absence of the presence or absence of the presence or absence of ring, absolute distance encoder, anti-vibration functions (antivibration lenses) equal-specification information.Then, in step In S540, the lens data of the mentioned kind chosen information is supplied to data processing division 312b (figure by data selecting section 312a 18).
Then, data processing division 312b, based on the lens data chosen by data selecting section 312a, carries out handing over to representing The information changing the title of camera lens 200 is the process (step S550) that camera lens name data carries out selection.Here, with Figure 22 described later The known expression camera lens title of the shown nonvolatile memory being stored in adapter control unit 310 that prestores and specification information it Between relation information (first above-mentioned chart-information) be comparison other, respectively with above-mentioned steps S540 in obtain camera lens number It is compared according to (above-mentioned specification information).Then, in fig. 22, selection has and the difference minimum of each lens data obtaining The camera lens title of (immediate) lens data, using the camera lens title as the exchange camera lens 200 being installed on adapter 300.
Next, data generating section 312c is in above-mentioned steps S550, generate the mirror chosen by data processing division 312b The data that first place claims, and add the camera lens name data of this generation, using as the exchange camera lens 200 being installed on adapter 300 A part for lens data, then generates the lens data (step sending to the first camera communications portion 112 of camera body 100 Rapid S560).
As described above, comprising to represent that exchanging camera lens 200 possesses in the information of the feature of the expression exchange camera lens 200 obtaining The species of optical system 220 information.In addition, in representing the information of species of optical system 220, comprising as above Any information in the information of optical characteristics representing optical system 220 and the information of function representing optical system 220 (represents Any information in the information of the specification of optical system 220, function, optical characteristics etc.).
In addition, corresponding with above-mentioned " first corresponding (chart) information " be represent optical system 220 species multiple The combination of information, corresponding expression exchange the information of the title of camera lens 200, using as known information.
Figure 22 is the figure representing one of the first corresponding informance example.
What Figure 22 represented is that each exchanges camera lens (multiple camera lens title) by information D50 and multiple information (characteristic information) The state of combination (group) pictorialization of D60, described information D50, represent known exchange camera lens (for example, as it is known that exchange Camera lens 200) known title information D50, the plurality of information (characteristic information) D60, represent that it known exchanges camera lens Optical system (for example, as it is known that exchange camera lens 200 optical system 220) species (specification).
In this Figure 22, in representing information D60 of species of optical system 220, comprise focal length and the information of open F value Using as the presence or absence of the presence or absence of the information of the optical characteristics representing optical system 220 and aperture ring, anti-vibration functions and electromagnetism aperture The information of the presence or absence of function is using the information as the function of representing optical system 220.That is, with the first corresponding informance shown in Figure 22 The combination of each information of corresponding information D60 being the species representing these optical systems 220, expression should have the friendship of a combination thereof Change information D50 of the title (title of the exchange camera lens 200 that in other words, should estimate) of camera lens based on a combination thereof.
For example, as described above, data processing division 312b be based on by data selecting section 312a select (above-mentioned steps S540) to Lens data and this first corresponding informance (Figure 22), select represent exchange camera lens 200 title information.
So, even if adapter 300 exchanges, connect, the information that camera lens 200 does not have a case that to represent camera lens title Down it is also possible to based on from the information exchanging the optical system 220 that camera lens 200 obtains, generate the information (camera lens representing camera lens title Name data).

So, even if adapter 300 exchanges, connect, the information that camera lens 200 does not have a case that to represent camera lens title Down it is also possible to the view data photographing with camera arrangement 1 corresponding shooting information, add based on exchange camera lens 200 information and generate expression camera lens title information (camera lens name data).
That is, even not having the exchange camera lens 200 of the information representing camera lens title, user also can be by via adaptation Device 300 and be connected with camera body 100, from the view data photographing learn carry out imaging process when the exchange camera lens that connects 200 title.Thus, even the exchange camera lens 200 of mutually different communication standard and camera body 100 are it is also possible to pass through Connect, suitably function via adapter 300.
In addition, in the above-described embodiment, using the chart data as shown in Figure 22,23, presumption has been made camera lens title, But can also be configured to, directly using above-mentioned specification information (optical characteristics information and the work(for example obtaining from exchange camera lens 200 Can information) at least a portion, to be made camera lens title.As an example, to the camera lens title shown in Figure 22 The exchange camera lens 200 of " Lname001 " is installed on adapter 300 and its indefinite situation of camera lens title " Lnama001 " is carried out Explanation.In this case, adapter 300 obtains optics as shown in figure 22 from the camera lens 200 that exchanges being installed on adapter 300 Characteristic information and function information, using as the specification information exchanging camera lens 200.That is, focal length 18-105, open F value are obtained 3.5-5.6, no aperture ring ("None" is set to " 0 "), have anti-vibration functions (" having " is set to " 1 "), no electromagnetism aperture function (0) this five The information of kind.The shot information that adapter control unit 310 can also be obtained using these, is made expression " 18-105_3.5- The data of this information of 5.6_010 ", and this data to be used directly as camera lens name data.Here, using five kinds of letters Breath whole and be made camera lens title but it is also possible to not using whole but be made using a part.Alternatively, it is also possible to direct Camera lens ID (for example, shown in Figure 23 a ID " AB0001 ") shown in Figure 23 to be used as camera lens title.
(conversion process of communications command (control command))
Then, in the first adapter communications portion 312, lead to as the first data for being taken at mutually different communication standard In letter system D1b and the first data communication system D1L, an example of the data processing of the matching of communications command of transmitting-receiving, right The conversion process of vibration Restrained Control order illustrates.
First adapter communications portion 312 carries out the order of the first data communication system D1b and the first data communication system D1L The relaying of data communication.
For example, the first adapter communications portion 312 passes through the communication process of the first data communication system D1b, from camera body The vibration Restrained Control order that 100 acquirements are controlled to VR drive division 235 (vibrationproof drive division), described VR drive division 235 (drive by vibrationproof Dynamic portion), the VR camera lens 223 (vibrationproof optical system) that exchange camera lens 200 is possessed is driven.
Then, the first adapter communications portion 312 will obtain vibration Restrained Control order, with the first data communication system D1L Communication standard coupling mode changed, and be sent to exchange camera lens 200.
In addition, in the present embodiment, camera body 100 to adapter 300, in initialization (the VR camera lens of vibration Restrained Control 223 initialization) when, send " initialization executes order " (the first control instruction), in addition, driving VR camera lens 223 entering to exercise When controlling the vibrationproof terminating to terminate to process, send and the initialization execution different orders of order i.e. " vibrationproof terminates order " (the Two control instructions).
Here, " initialization executes order " is to be used for VR camera lens in the communication standard of the first data communication system D1b 223 carry out the order processing of feeling relieved." vibrationproof terminates order " of another aspect is the communication mark in the first data communication system D1b For making VR camera lens 223 to the mobile and standby order of the position of readiness different from centered positions in standard.So, in the first data On the communication standard of communication system D1b, this two orders (" initialization executes order " and " vibrationproof terminates order ") are to exchange The mutually different order of content that camera lens 200 is processed.But, in the communication standard of the first data communication system D1L, no There are two consistent with this two orders respectively orders.
But, on the communication standard of the first data communication system D1L, even if in the initialization process of vibration Restrained Control and anti- Under either case in end of shaking process, also (common will be used for executing one of the process making the position of VR camera lens 223 feel relieved ) centering order (the 3rd control instruction) exports the mode exchanging camera lens 200 specifying.Then, in exchange camera lens 200 side, According to its centering order, execution will carry out the process of locking after the position centering of VR camera lens 223.
Therefore, adapter 300 is configured to, in order to eliminate related above-mentioned two communication system of vibration Restrained Control order (D1b and D1L the mismatch on communication standard between), by the species (control instruction content) of the first data communication system D1b use no Same order (initialization execution order and vibrationproof terminate order) is in the order being converted to the first data communication system D1L use When, be converted to a common order (centering order).So, by being indirectly situated between in adapter 300, it is capable of possessing logical Communication between the camera body 100 of the accurate mutually different communication system of beacon and exchange camera lens 200 and control.
So, the first adapter communications portion 312 is in the process of vibration Restrained Control, to by the of mutually different communication standard The communications command of one data communication system D1b and the communication of the first data communication system D1L carries out conversion relaying.
That is, the first adapter communications portion 312 controls life by mutually different for the command content receiving from camera body 100 Make (the hereinafter referred to as first control instruction, the second control instruction), be converted to a common control exchanging camera lens 200 transmission System order (the hereinafter referred to as the 3rd control instruction).Here, the first adapter communications portion 312 will be used for exchanging camera lens 200 to driving The control instruction that the VR drive division 235 of the VR camera lens 223 possessing is controlled is that control command is sent to exchange camera lens 200, with As the 3rd control instruction.
For example, the first adapter communications portion 312 receives from camera body 100 and makes to comprise by the beginning of the state of exchange camera lens 200 " initialization executes order " of the initialization process execution of the process of beginningization, using as the first control instruction.Then, the first adaptation Device communication unit 312 executes order according to the initialization from camera body 100, will comprise to make the position of VR camera lens 223 feel relieved (moving to predetermined position) " centering order " executes life in the initialization (initialization of VR camera lens 223) of interior vibration Restrained Control Order is sent to exchange camera lens 200, using as the 3rd control instruction.
That is, the first adapter communications portion 312 executes order with receiving to initialize from camera body 100, is converted into The initialization execution of the vibration Restrained Control comprising centering order is ordered and is sent to exchange camera lens 200.
In addition, the first adapter communications portion 312 receives the " anti-of the control end making VR drive division 235 from camera body 100 End of shaking is ordered ", using as the second control instruction.Then, the first adapter communications portion 312 is according to from camera body 100 Vibrationproof terminates order, (the moving to predetermined position) felt relieved in the position making VR camera lens 223 " centering order " (with " initial Change and execute order " changed after order common order) be sent to and exchange camera lens 200, using as the 3rd control instruction.
That is, the first adapter communications portion 312 terminates order with from camera body 100 reception vibrationproof, and it is fixed to be converted into Heart order and be sent to exchange camera lens 200.
In addition, above-mentioned position centering is to be moved into predetermined position.
Predetermined position is can in the case of making after VR camera lens 223 exciting in the moveable scope of VR camera lens 223 Guarantee the position of the amplitude of regulation.For example, predetermined position is the position being in central authorities in the moveable scope of VR camera lens 223 Put.
So, adapter 300 can be converted to and the vibration Restrained Control order receiving from camera body 100 to exchange Camera lens 200 send communication standard corresponding vibration Restrained Control order and send.
In addition, the first adapter communications portion 312 the control instruction receiving from camera body 100 be not with will to exchange mirror It is also possible to carry out not sending out this not corresponding control instruction in the case of the corresponding control instructions of control instruction of 200 transmissions Deliver to the control exchanging camera lens 200.
For example, under vibration Restrained Control holding state (state that vibration Restrained Control temporarily ceases), there is VR camera lens 223 mechanically The camera lens (for example, being set to exchange camera lens 200) of static composition, VR camera lens 223A are electrically driven and the mirror of static composition The camera lens of head (for example, being set to exchange camera lens 200A) this different composition.
In the case of being connected with exchange camera lens 200A on camera body 100, the first camera communications portion 112 is by VR mirror When head 223A controls to vibration Restrained Control holding state, exchange camera lens 200A is sent makes its static preventing for electrically driving Shake and control standby control instruction.
On the other hand, in the case that exchange camera lens 200 is connected with via adapter 300 on camera body 100, first Camera communications portion 112 when VR camera lens 223 is controlled to vibration Restrained Control holding state, to 312, the first adapter communications portion Send the control instruction that vibration Restrained Control is standby, using as common control.
Here, in exchanging camera lens 200, when controlling to vibration Restrained Control holding state, because VR camera lens 223 is mechanically quiet Only, therefore do not need the standby control instruction of above-mentioned vibration Restrained Control.
Therefore, the first adapter communications portion 312 carries out not treating the vibration Restrained Control obtaining from the first camera communications portion 112 The control instruction of machine is sent to the control exchanging camera lens 200.
So, adapter 300 can carry out not needing from the order that camera body 100 receives to exchange camera lens The control that the order of 200 transmissions sends.Thus, adapter 300 can not comprise to exchange camera lens to exchanging camera lens 200 and sending The order of unwanted order for 200.
Then, with reference to Figure 24, the processing sequence of the initialization process to vibration Restrained Control illustrates.
Figure 24 is the figure representing one of processing sequence of initialization process of vibration Restrained Control example.
